Hmm, can we all say swine flu? Well that’s only one reason why one would vomit. Actually any flu could make someone vomit. Food poisoning can also make someone vomit. Some pregnant women can vomit during their pregnancy, because of the change in their hormones. And some people vomit from seeing or smelling something repulsive. And there’s some people that vomit from overeating, and drinking too much alcohol. Then the stomach says ‘ENOUGH’, and takes the drivers seat, while the mind gets it’s senses back.
